JULIUS L. STENSBY, OF EVANSVILLE, WISCONSIN.

CHECK-ROW CORN-PLANTER.

To all whom it may concern:

Be it known that I, J ULIUS L. STENsBY, a citizen of the United States, residing at Evansville, in the county of Rock and State of Visconsin, have invented certain new and useful Improvements in Check-Row Corn- Planters, of which the following is a specification.

This invention relates to improvements in check-row corn planters and its object is to produce a device of this class having a marker adapted to be instantly transferred from one side of the planter to the other when desired.

Another object is the provision of means for regulating the depth of the impression made by the marker in the ground; in hard ground greater pressure or weight is necessary to make an impression than in soft ground.

Other objects are cheapness of manufacture, eiiiciency and durability.

ith the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claims and illus trated in the accompanying drawings which form a part of the said specification and in which Figure 1 is a plan of a corn planter embodying my improvements. Fig. 2 is a side elevation. Fig. 3 is a detail of the marker and mechanism for rotating the same from one side of the planter to the other and for regulating the depth of the impression made by the marker.

Like reference characters indicate corresponding parts throughout the several views.

1 is the frame of the planter supported upon suitable traction wheels 2. A plate 3 is secured to the main frame 1 and standards or arches 1, 5 and 6, the standard 4: terminating in a serrated segment'tflare secured upon this plate.

6 is a wheel having a serrated periphery journaled between the standards or arches 4 and 5 and a lever 7 is secured to one end of the axle for rotating the same, the said lever being provided with a spring catch 8 for engagement with the teeth of the segment 4.

Specification of Letters Patent.

Application filed September 22, 1911.

Patented July 9, 1912.

Serial No. 650,715.

9 is a toothed transmission wheel supported upon its axis 10 between the standards or arches 4L and 5 in contact with the wheel 6' and to one end of the axis 10 and between the standards or arches 5 and 6 an arm 11. is secured oscillative with the wheel 9. A sleeve 12 is adjustably secured to the arm 11 and is provided upon its upper surface with a recessed guide 13 for the retention of a slidable weight 1 1 which may be locked at any desirable position in the guide. The purpose of the weight is to increase the downward pressure at the remote extremity of the sleeve 12 when it is desired to make a deep impression in the ground or an impression in hard ground. WVhen not desired the weight may be removed by withdrawing the bolt which holds it in position.

At the remote or free extremity of the sleeve 12 the wheel 15 with marker 16 is provided. It is readily seen that by raising the spring catch 8 out of engagement with the segment 4 and rotating the lever 8 in one direction the wheel 6 will be rotated in the same direction and the transmission wheel 9 and arm 11 with sleeve and marker will be rotated in the opposite direction to the other side of the machine if desired.

What I claim is 1. In a corn planter, a plurality of standards secured to the main frame, one of the standards terminating in a serrated segment, a toothed wheel journaled in the said standards, a lever secured to the axle of said wheel, a transmission wheel journaled in the said standards in contact with the first mentioned wheel, an arm secured to and oscillative by the axle of the transmission wheel, a sleeve carried by said arm, a marker carried by said sleeve and means arranged on said sleeve for regulating the depth of the impression made by the marker.

2. In a corn planter, a plurality of standards secured to the main frame, one of the standards terminating in a serrated segment, a toothed wheel journaled in the said standards, a lever secured to the axle of said wheel, a spring catch carried by said lever for engagement with the aforesaid serrated segment, a transmission wheel journaled in the said standards in contact with the first mentioned wheel, an arm secured to and oscillati've by the axle of the transmission as my own I have hereto aiiixed my signa- Wheel, a sleeve secured upon said arm, a ture in the presence of two subscribing Witguide carried by said sleeve, a removable nesses.

Weight slidable in said guide and a marker JULIUS L. STENSBY. carried at the free extremity of the said Witnesses: sleeve. L. E. MARTIN,

In testimony that I claim the foregoing H. S. SOI-IELDRUP.
